Cvt rate on commercial areas

Salam to all..
As this is my first question at zameen.Com and hopefully gurues will reply and answer the question.
The cvt on residential plots is 0% below 999 sq.Ft.Of land area. And 2% at land area between 1000-2199 sq.Feet & 2.5% on above land area.. Is it correct? And what cvt rates apply on different commercial sizes?
